It *may* have a negligible effect on those consuming a Standard  
American Diet.  The question for paleo dieters though is what effect  
does coffee have on us, whose systems are not a milkshake of  
competing nonpaleo influences?  We have no studies, which is why the  
paleo yardstick is so valuable.

Having said that, I like the "I know it's not paleo, but I'm doing it  
anyway" answer.  I do that for wine, though I've reduced my  
consumption considerably in the new year.  But we would all do well  
to pay attention to our bodies -- no way paleo man was consuming so  
much caffeine for one.  That's to say nothing of the other clearly  
unpaleo substances coffee.

Cheers.
